2,2′-四甲撑二氧二(8-N-水杨叉亚胺萘)铜配合物的晶体结构

Crystal Structure of 2,2' -Tetramethylene-Dioxodi(8-N- Salicylideneimino-naphthalene) Copper Complex

标题配合物的晶体结构已用X射线衍射确定。它属单斜晶系,空间群为P2_1/a,晶胞参数为:a=9.824(3),b=35.530(9),c=17.552(6),β=98.97(2)°,V=6053(4)~3,Z=8。结构通过Patterson函数和Fourier技术解出,用块矩阵最小二乘法修正,最后偏差因子R=0.064。该配合物是反式平面配合的加帽结构,平均键长Cu—O=1.870,Cu—N=2.007,存在两个独立的结晶学分子。

The crystal structure of the title complex was determined by X-ray diffraction. It belongs to the monoclinic system, space group is P21/a with cell dimensions a =9. 824(3) A , b=35. 530(9) A. c=17.552(6)A,β=98. 97(2)°, V=6053(4)A3 and Z=8. The structure was analyzed by Patterson and Fourier technique and refined by block-matrix least squares to final residual factor of R = 0. 064. The complex is a trans-planar 'capped' structure, with average bond length Cu-O 1. 870 A ,Cu-N 2. 007A. There are two crystallographically independent molecules.
